I Corps Support Command (I COSCOM) is responsible for keeping I Corps in the fight. It's main focus is MAFFMS: Manning, Arming, Fueling, Fixing, Moving the force, and Sustaining the soldiers. This includes most functions that are essential to modern warfighting, except for pulling a trigger.
Operationally, each division will typically be supported by a Corps Support Group (CSG). This CSG will provide supply and transport, maintenance, and medical support above the division level.
